Researchers create rollerball-pen ink to draw circuits

June 28, 2011 by Bob Yirka report

University professors create rollerball-pen ink to draw circuits

Image: Wiley

(PhysOrg.com) -- Two professors from the University of Illinois; one
specializing in materials science, the other in electrical engineering, have
combined their talents to take the idea of printing circuits onto
non-standard materials one step further by developing a conductive ink that
can be used in a traditional rollerball ink pen to draw circuits by hand onto
paper and other porous materials. In their paper published in Advanced
Materials, team leads Jennifer Lewis, Jennifer Bernhard and colleagues
describe how they were able to make a type of ink from silver nanoparticles
that would remain a liquid while in the pen, but would dry like regular ink
once applied. The pen could was then used to draw a functioning LCD display
and an antenna.

To make the ink, the team produced silver nanoparticles by reducing a silver
nitrate solution along with an acid to prevent the particles from growing too
large. Afterwards the acid was removed and the viscosity of the ink modified
using hydroxyethyl cellulose to get just the right consistency. The result is
a sort of liquid metal that dries on contact and which can be used to conduct
electricity, hence its ability to be used in the creation of a circuit.

Silver pen has the write stuff for flexible electronics

University of Illinois engineers developed a pen with conductive silver ink
that can write electric circuits and interconnects directly on paper and
other surfaces. Credit: Bok Yeop Ahn Up till now, most research on printing
circuits onto non-standard materials, such as paper, have been done using
inkjet printers or even airbrushes. This new approach would allow circuits to
be drawn quicker and much cheaper, or even on-the-fly, as no other hardware
is needed. Such a low cost device might create a market for throwaway
circuits or even super cheap batteries. Paper was used in the study because
it is considered to be the most suitable non-standard material for printing
circuits due to its wide availability, low cost, ability to be bent and
shaped, and the fact that it is biodegradable.

Lewis noted that the paper used in study was folded after testing to see how
the circuit would hold up, and discovered it took folding several thousand
times before the ink pathways were broken. She also noted that other
materials besides paper could be used, such as wood or ceramics.

lines form the interconnects between the LEDs. Credit: Bok Yeop Ahn The team
next plans to look into other types of materials that might be used to make
conductive ink for their pen, hoping to open up the door to all kinds of inks
that can be used for a wide variety of purposes.

Abstract

Pen-on-paper flexible electronics are fabricated using a conductive silver
ink-filled rollerball pen. This approach provides a low-cost, portable route
for fabricating conductive text, electronic art, interconnects for light
emitting diode (LED) arrays, and three-dimensional (3D) antennas on paper.

There's an interesting solicitation from  the US gov't at

http://lab.challenge.gov/

They are looking for cool, informative lab activities for K-12
students -- a chance to make a positive impact and potentially gain
some exposure/awareness for the group (or yourself).  This particular
challenge doesn't come with a cash prize, but there may be others down
the road that do.
